Summary
In Iskandar bin Rahmat v Public Prosecutor ([2017] SGCA 9), the Court of Appeal dismissed an appeal against convictions for two counts of murder under s 300(a) of the Penal Code (Cap 224, 2008 Rev Ed), punishable with death under s 302(1). The appellant, an investigation officer with the Singapore Police Force, argued that although he stabbed two victims and caused fatal injuries, the evidence did not establish an intention to cause death. He contended that, at most, his actions showed an intention to cause injuries sufficient in the ordinary course of nature to cause death, which would fall under s 300(c) and avoid the mandatory death sentence.
More significantly, the appellant relied on multiple “exceptions to murder” under s 300 to seek a conviction for culpable homicide not amounting to murder, and a consequential sentence under s 304(a). He invoked Exception 2 (exceeding the right of private defence), Exception 4 (sudden fight), and Exception 7 (diminished responsibility). In addition, he filed two criminal motions seeking leave to adduce fresh forensic pathology and psychiatric reports. The Court of Appeal rejected the appeal and refused the motions, upholding the High Court’s findings on intention and the non-applicability of the exceptions.
What Were the Facts of This Case?
The appellant, Iskandar bin Rahmat, was convicted of murdering two victims: Mr Tan Boon Sin (“D1”) and D1’s son, Mr Tan Chee Heong (“D2”). The convictions arose from events that occurred on 10 July 2013, following a planned robbery. The Court of Appeal noted that the broader background facts were comprehensively set out in the High Court decision (Public Prosecutor v Iskandar bin Rahmat [2015] SGHC 310), and that most of those facts were not disputed. The central factual dispute on appeal concerned what happened inside D1’s house over a period of about 30 minutes.
Before the incident, the appellant experienced serious financial difficulties and was at risk of losing his job. He devised a plan to rob D1, who had stored a substantial sum of money in a safe deposit box at Certis CISCO (“CISCO”). The appellant knew about the safe deposit box arrangements because he had previously come across a police report filed by D1 regarding missing monies. His plan involved calling D1 and introducing himself as a police officer, informing D1 that the safe deposit box would be “hit” and instructing him to remove the contents so that the appellant could place a CCTV camera inside the box. The appellant prepared a dummy CCTV camera and placed it in a box.
On the day in question, the appellant met D1 near CISCO and executed his plan. D1 initially did not carry out the instructions because the dummy camera and box could not fit into the safe deposit box. After returning to the petrol station, the appellant told D1 that the camera could be placed without its box. D1 complied, successfully placing the camera into the safe deposit box. D1 then removed the monies (in excess of $600,000) and stored them in an orange bag. The appellant then followed D1 in D1’s car to D1’s house, ostensibly to escort him because D1 was carrying a lot of money.
Inside D1’s house, the appellant did not dispute that he stabbed both D1 and D2 and that the injuries were fatal. His defence was that, on his account of events, he did not intend to cause death. Instead, he claimed that his actions were driven by panic and fear during a struggle, and that he was trying to escape rather than to kill. The appellant’s narrative began with his attempt to grab the orange bag and run, which he said he could not do because the outer gate was closed and he did not know how to open it. He then claimed he persuaded D1 to open the gate so he could smoke, and later asked to use the toilet. When he came out, he said the orange bag was no longer by the staircase, and he panicked.
According to the appellant, D1 was in the living room using his mobile phone and appeared to discover that the CCTV camera lacked batteries. D1 then approached the appellant, brandished a knife, and attacked him. The appellant alleged that he grabbed D1’s hand, wrested the knife, and stabbed D1 multiple times, including around the neck area. He said he was not aiming to kill or to target vital areas, but rather to get D1 off him so he could run away. The appellant then described a second struggle when D2 charged at him from the front door. He claimed he blocked D2’s initial blow and intended to retaliate by punching, but he ended up stabbing D2 because he did not realise the knife was still in his hand. He maintained that he was again trying to escape and that he did not aim at any particular part of D2’s anatomy. After D2 fell and later ran out of the house, the appellant left, abandoning any intention to retrieve the orange bag, and attempted to deal with his injured hand.
What Were the Key Legal Issues?
The appeal raised several interrelated legal issues. The first was whether the evidence supported the conviction for murder under s 300(a) of the Penal Code, which requires proof that the accused intended to cause death. The appellant argued that the prosecution had not established the requisite intention to kill. Instead, he maintained that the facts, properly analysed, showed only an intention to cause injuries sufficient in the ordinary course of nature to cause death, which corresponds to s 300(c) and attracts a different sentencing regime.
The second set of issues concerned the applicability of exceptions to murder under s 300. The appellant sought to rely on Exception 2 (exceeding the right of private defence), Exception 4 (sudden fight), and Exception 7 (diminished responsibility). Each exception has distinct legal requirements, and the appellant’s case required the Court of Appeal to examine whether the factual matrix—particularly the nature and context of the stabbing—could satisfy those requirements on the evidence.
Finally, the Court of Appeal had to consider the appellant’s procedural applications to adduce fresh evidence. The appellant filed Criminal Motion No 14 of 2016 to adduce a forensic pathology report dated 13 July 2016 by Dr Ong, and Criminal Motion No 17 of 2016 to adduce a forensic psychiatric report dated 3 August 2016 by Dr John Bosco Lee. The Court therefore had to determine whether the proposed reports met the threshold for “fresh evidence” on appeal and whether they could affect the outcome.
How Did the Court Analyse the Issues?
The Court of Appeal approached the appeal by focusing on intention and the exceptions to murder, while also addressing the fresh evidence motions. On intention, the Court considered the appellant’s conduct and the circumstances surrounding the stabbings. Although the appellant asserted that he did not intend to kill and that he was acting out of panic and fear, the Court examined whether the objective facts and the pattern of violence were consistent with an intention to cause death. The Court’s analysis reflected the principle that intention is a matter of inference from the totality of the evidence, including the nature of the weapon used, the manner of attack, and the extent and location of injuries.
In this case, the appellant stabbed D1 and D2 in circumstances that involved close physical confrontation and repeated stabbing. The Court noted that the appellant did not dispute the stabbing and fatal injuries, but argued that he lacked the intention to cause death. The Court’s reasoning emphasised that repeated stabbing, particularly in areas such as the neck, is capable of supporting an inference of intention to cause death. The Court also considered the appellant’s own account that he stabbed D1 five to six times and that the autopsy reports showed more wounds, suggesting that the violence was not a single impulsive act but involved sustained aggression during the struggle.
With respect to Exception 2 (exceeding private defence), the Court examined whether the appellant’s actions fell within the scope of lawful private defence and, if so, whether he exceeded it. The appellant’s narrative framed the stabbing as a response to D1’s and D2’s attacks. However, the Court assessed whether the appellant’s defensive response was proportionate and whether the factual circumstances supported the legal characterisation of his conduct as an “exceeding” of private defence rather than an unlawful attack. The Court’s analysis indicated that where the evidence supports that the accused continued to stab in a manner inconsistent with a defensive necessity, the exception cannot be invoked.
Similarly, for Exception 4 (sudden fight), the Court considered whether there was a “sudden fight” between the parties, and whether the appellant’s participation and the temporal and causal connection between the fight and the fatal injuries satisfied the exception’s requirements. The appellant’s case attempted to characterise the events as chaotic and panicked reactions during a struggle. The Court, however, evaluated whether the confrontation met the legal threshold of a sudden fight as understood in the Penal Code framework, and whether the appellant’s actions were sufficiently connected to that fight in a manner that would reduce murder to culpable homicide not amounting to murder.
For Exception 7 (diminished responsibility), the Court considered the appellant’s reliance on a psychiatric report. Exception 7 requires proof that the accused was suffering from an abnormality of mind that substantially impaired his mental responsibility at the time of the offence. The Court therefore had to examine both the admissibility of the psychiatric evidence and, assuming admissibility, whether it established the statutory requirements. The Court’s approach reflected the caution with which diminished responsibility must be established: it is not enough to show distress or panic; the evidence must demonstrate a qualifying abnormality of mind and a substantial impairment of responsibility linked to the offence.
On the fresh evidence motions, the Court addressed whether the proposed forensic pathology and psychiatric reports could be admitted on appeal. The Court’s analysis would have considered whether the reports were genuinely “fresh” in the relevant sense, whether they could not have been obtained earlier with reasonable diligence, and whether they were likely to be credible and materially relevant to the issues. The Court ultimately refused the motions, indicating that the proposed evidence did not meet the threshold or did not alter the legal conclusions reached by the High Court.
What Was the Outcome?
The Court of Appeal dismissed the appeal and upheld the appellant’s convictions for two counts of murder under s 300(a) of the Penal Code. The Court also refused the criminal motions seeking leave to adduce the forensic pathology and psychiatric reports. As a result, the appellant remained liable to the mandatory sentencing consequences applicable to murder under the Penal Code framework upheld by the courts below.
Practically, the decision confirms that where the evidence supports an inference of intention to cause death—particularly through repeated stabbing in close proximity—the defence arguments that the case falls under s 300(c) or that one or more exceptions to murder apply will face significant hurdles. The refusal of the fresh evidence motions further underscores the appellate court’s gatekeeping role in ensuring that new expert material does not undermine finality without meeting strict admissibility and relevance requirements.
Why Does This Case Matter?
Iskandar bin Rahmat is significant for practitioners because it illustrates how Singapore appellate courts evaluate (i) intention in murder cases and (ii) the narrow scope of exceptions to murder. The case demonstrates that an accused’s subjective assertion of panic or fear does not automatically negate intention. Courts will infer intention from objective circumstances, including the nature of the weapon, the manner of attack, and the pattern and location of injuries.
The decision is also useful for lawyers dealing with diminished responsibility and private defence exceptions. Exception 7 requires more than general mental disturbance; it requires an abnormality of mind that substantially impairs responsibility. Similarly, Exception 2 and Exception 4 require careful factual and legal characterisation of the confrontation. Defence counsel must therefore marshal evidence that squarely satisfies the statutory elements rather than relying on broad narratives of struggle.
Finally, the case provides guidance on the procedural dimension of adducing fresh evidence on appeal. Expert reports—whether forensic pathology or psychiatric—will not be admitted merely because they exist after trial. They must satisfy the appellate threshold for fresh evidence and be capable of materially affecting the outcome. This is a reminder that appellate strategy must be grounded in both evidential admissibility and substantive legal relevance.
